Outdoor Research Men's Helium Jacket:
The Men's Outdoor Research Helium Jacket is a compressible storm shell that's so light it practically f, or at least it’s so light that you won’t notice you’re carrying it until a sudden downpour bursts into your day. When a big, exposed objective puts you on route for a full day stretching into dark, this jacket packs into its own pocket and can be clipped to your harness for quick access if you need protection from rain, wind, or cooling temps. And it includes all the features needed for true functionality, without any bulky excess.
